Why we have Arrays and Array in Java

Question

I have run into these two documentations:

• Java documentation for the class Array
• Java documentation for the class Arrays

and I\'m wonde

Answer 1

The differences are made fairly clear in the docs.

From Arrays.java:

This class contains various methods for manipulating arrays (such as sorting and searching). This class also contains a static factory that allows arrays to be viewed as lists.

From Array.java

The Array class provides static methods to dynamically create and access Java arrays.

Essentialy Array is an implementation of core Array operations - getting, setting and instantiation.

Arrays is a helper class for wrapping common Array operations (conversion between Arrays and Lists, sorting, searching for a value) without polluting the core Array "api".
